I’ve been in an automating mood lately – old school, batch script style.
Here’s another one I cooked up to relieve you of tedious steps needed to turn off all advanced networking features in
Windows 2008/Vista/7.
I added before and after logging for fun.
As a side note, I was not able to cook up a way to dynamically enumerate network connections and uncheck the IPv6 protocol for you…this is still done manually. Perhaps with more time, I could fix this.
Regardless, this little batch file has saved me a bit of time already.
Again, use all but the asterisks for the batch file…

-> update 15 Sept 2010
Per SBS 2008 BPA, I see that the tool throws warnings when the autotuning, rss, taskoffload, and congestion are enabled (as they are by default).
I added the line for taskoffload in to the script above for your copy-and-paste pleasure!
